Physical activities can be categorized by the energy systems they utilize: the anaerobic A-lactic system for short high-intensity bursts, the anaerobic lactic system for moderate activities, and the aerobic system for long-duration exercises. Examples include sprints and powerlifting for anaerobic systems, and long-distance running for aerobic activities. Understanding these systems helps in designing effective training routines.

Physical activities utilize three primary energy systems: anaerobic A-lactic for short bursts, anaerobic lactic for moderate intensity, and aerobic for longer duration activities. Examples include sprints for anaerobic A-lactic, middle-distance runs for anaerobic lactic, and long-distance running for aerobic. Knowledge of these systems is essential for tailored fitness training. ;
